Provided is an object detection apparatus and an object detecting method for, with respect to an object detected by a radar, determining whether the object is an automobile and performing an appropriate collision determination based on a determination result. The system includes first and second sections. Usage rights are used to define how a digital work may be used or distributed. The separated epithelium may be lifted or peeled from the surface of the eye to form an epithelial flap or a pocket. Another embodiment performs the steps at different energies for spectroscopic detectors. Numerous other embodiments are also within the scope of the present disclosure.
